I cut the front cross bar & fit the drawbar & welded it in, then took it outside to sit it behind the shorty. to see how long I wanted the drawbar. The other thing I'm trying to decide on is where to put the spare wheel. either on the front or if to make a swingout carrier & put it on the rear.

I'm still trying to decide where to put the spare wheel. I modified an old spare carrier this afternoon to see if I like it on the back or not. I need to make up my mind because if it goes on the back I'll have to put the anchor plates in the frame before I put the skin on.

Go the front, you'll get sick of swinging it out the way all the time, it can't get in the way up front.

it wouldn't hurt to have some weight in front of the axle.
As it stands you must have about 5kg of ball weight which is a bit scary.
with the wheel & tyre on the back i reckon it would lift off the ball.

lay it down on the drawbar to lower the centre of gravity a bit because lets be honest it would take much to roll it over at the moment. i had a series 1 landrover tub trailer only on 31's and nearly rolled it with 2 dirt bikes in the back from a rut in a gravel road. laying it down gives you somewhere to put stuff too, we're always looking for somewhere to put loaded rubbish bags after a camping trip

Thanks for the input guys.
Oversite, if it goes on the back it will have to swing out because I am making the tailgate swing out.
Eddy that's not such a bad idea.
Monkeybucket, the tyres are the same as on the shorty. They are 15x10 rims & 35x12.5 rubber. Gives it character hey.
Doowrag, I need to work out some how to measure drawbar weight to see what I have.

I added some more rails to support the draw bar & then finish welding the trailer chassis. I just have to add mounts to it now to bolt the body down to.

I also wasn't happy with the angle of the shackles either. I did a bit of a suspension test (jumping up & down on the trailer) & the rear of the springs were bottoming out on the chassis, so I cut off the mounts & moved them back a bit.

I also had a bit of a think about the position of the spare. I measured the tow ball weight & it looks like it will have to sit up front because with it on the back, it's actually lifting the weight off the tow ball.
